DETERMINATION OF DEMAND The Demand shall be the registered integrated average load in kVA measured in the 15-minute interval in which such average load in kVA is highest during the applicable period. FOREIGN EXCHANGE ADJUSTMENT The Foreign Exchange Adjustment in force at the time shall apply to all charges except Fuel and IPP Charge under this schedule. The requisite terms and conditions of the Foreign Exchange Adjustment provision are set out in the Additional Terms and Conditions hereto. TERMS OF CONTRACT A contract for a period of three (3) years may be required as a condition of service. ADDITIONAL TERMS AND CONDITIONS FUEL AND IPP CHARGE The Fuel Charge represents the total cost of fuel (including the cost of fuel for energy purchased from Independent Power Producers) required to produce and deliver kilowatt-hour of electricity. The cost of fuel per kilowatt-hour shall be calculated each month on the basis of the total fuel computed to have been consumed by JPS and Independent Power Producers (IPPs) in the production of electricity, adjusted for the applicable System heat rate and system losses. The applicable System heat rate is 11,200 kJ/kWh, and is a combination of the Company’s generating heat rate and the IPP’s generating heat rate as per contract with the IPPs. The applicable value of system losses is 15.8% of total net generation of the Company and Independent Power Producers delivered to the grid. The term, Independent Power Producers (IPPs), includes private suppliers from whom JPS purchases electricity in bulk for transmission and distribution. The IPP Charge represents the difference between the IPP costs included in the base Customer, Demand and Energy Charges and the actual IPP non-fuel costs payable and/or paid by JPS. The Fuel and IPP Charge shall be:

• combined as a single line item on the customer’s bill,

• a monthly amount per kilowatt-hour,

• calculated in US dollars and be converted to Jamaican dollars at the Billing Exchange Rate,

• divided by billed kWh sales and be applied to all sales.

The Fuel and IPP charge per kilowatt-hour shall be calculated to the nearest one thousandth of a dollar. Where a bill straddles two months the latest Fuel and IPP Charge shall be used for billing purposes. CHARACTER OF SERVICE Notwithstanding the Terms of Contract provision, JPS may at its option after three months’ notice and advice to the customer, shift customers to an appropriate rate class, if it is determined that the customer’s character of service over the previous 12-month period fits that of another class. FOREIGN EXCHANGE ADJUSTMENT All charges excluding the Fuel and IPP Charge are subject to a Foreign Exchange Adjustment. The charges excluding the Fuel and IPP Charge will be increased or decreased by a percentage computed as follows:

Billing exchange rate – Base exchange rateBase exchange rate

x 76%FE Adjust =Billing exchange rate – Base exchange rate

Base exchange ratex 76

Billing exchange rate – Base exchange rateBase exchange rate

Billing exchange rate – Base exchange rateBase exchange rate

x 76%FE Adjust =

Note: 1. The base exchange rate is J$68.00:US$1.00. 2. The Billing Exchange Rate which is shown on the face of the bill shall be the

arithmetic mean of the daily weighted average of rates at which financial institutions in Jamaica sell United States Dollars for Jamaican Dollars on the Spot Market (the "Spot Market Weighted Average Selling Rate") issued by the Bank of Jamaica for the last trading day of the month preceding the month of billing. If no such rate is issued the last trading day by the Bank of Jamaica or, if the current system for determining the rate at which United States dollars are exchanged for Jamaican dollars shall have changed then, for the purpose of this provision, the rate for that day shall be the weighted average of the rates at which Commercial Banks in Jamaica sell United States dollars for Jamaican dollars on that same day as determined by the Jamaica Public Service Company. Where the billing period exceeds one month, that rate shall be the arithmetic mean of the monthly Billing Exchange Rates determined in accordance with the foregoing.

ANNUAL ADJUSTMENT CLAUSE All charges excluding the Fuel and IPP Charge shall be adjusted on June 1st of each year to reflect Jamaican inflation, US inflation, change in the weighted average US selling Exchange Rate rounded to the nearest Jamaican dollar and issued by the Bank of Jamaica in and about March 31, of each year and efficiency and quality of service factors. The annual Jamaican inflation rate shall be based on the most recent published values of the Statistical Institute of Jamaica (STATIN) All Group 12-month point-to-point Consumer Price Index (CPI) at February 28 each year. The annual US inflation rate shall

- 20 –

be based on the most recent published 12-month point-to-point Consumer Price Index, all urban consumers, US city average, US Department of Labor, Bureau of Labor Statistics, published monthly at March 31 each year. The Annual Adjustment shall be computed as follows: BRn = BR(1 + dI ± X ± Q ± Z) Where: dI = annual growth rate in inflation and devaluation. X = 0 until May 31st 2006 and 2.72% thereafter.

Q = an adjustment allowed by the OUR to reflect changes in the quality of service provided to customers. Z = any adjustment approved by the OUR to reflect events that affect JPS’ costs, which are not due to JPS’ managerial decisions and which are not captured by other elements in the price cap mechanism.

dI = 0.76 ((EXn – Exb)/ Exb) (1 + 0.92INFus) + (0.76)(0.92) Ius + 0.24 INFj

EXb = Base Exchange Rate EXn =The New Base Exchange Rate INFus = US inflation rate INFj = Jamaican inflation rate.

RECONNECTION FEE The Reconnection Fee is applicable to all Rate Categories. Effective June 1, 2004 the Reconnection Fee shall be $1,441.00. Thereafter JPS shall be entitled to charge its customers a Reconnection Fee which shall be determined by June 30 each year and which shall be based on the actual cost of undertaking reconnections in the preceding fiscal year plus a ten percent (10%) service charge PROVIDED THAT the said actual cost was incurred in the most cost-efficient and cost-effective manner. In the absence of a determination the existing rate shall continue in force. Other charges for services or changes in these schedules approved by the Office of Utilities Regulation will be published from time to time.
